HENRY SIMON, 0F PROVIDENCE, RHODE ISLAND.

SHIRT-STUD.

Specification of Letters Patent No. 27,888, dated April 10, 1860. Y

To all whom tt may concern:

Be it known that I, HENRY SIMON, of Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Shirt Studs and Buttons; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the acompanying drawings, forming part of this specification, in which- Figure 1, is a front view of a portion of a shirt bosom, containing a stud with my improvement. Fig. 2, is a section of the stud in a plane parallel with the face, on an enlarged scale. Figs. 8 and 4, are central transverse sections of the same taken parallel with the length of the hole provided in the garment to receive it. Fig. 5 is a central transverse section of the same taken transversely to the said hole.

Similar letters of reference indicate corresponding parts in the several figures.

My invention consists in providing a stud or button with a hook like shank fitted to slide in a slit in the back of the head under the control of a spring within the head as hereinafter described whereby it is made to operate in combination with a fixed shank of similar form to secure the stud or button in the holes provided for it in a garment, and fasten the garment very securely and whereby also provision is aiforded for the insertion of the stud or button into and its withdrawal from the holes very easily.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, is the head of the stud made with a radial slot a, in the back for the movable shank b, to slide in, said slot being radial to the' center of the head, and extending from one side or very near it beyond the center. In order to provide for the insertion of this shank in the slit a, the head A, is made hollow of two pieces, and the shank is put into the slot from the edge of the back, before the back and front are united the part fitting to the said slot having its sides grooved to keep it in its place.

c, is the spring attached to the interior of the back and pressing upon the portion of the shank b, within the head in such a manner as to force it outward. This spring may be of any suitable form.

(Z, is the fixed shank of the saine form as b, that is to say like a hook but having its back part straight and parallel with the back of the head, and set in the opposite direction to Z), with its extremity away from the center of the head. This shank d, is attached to the back of the head close to the inner end of the slot a.

The holes e, e, provided to receive this stud or button are of the form of ordinary button holes but may be considerably shorter than the diameter of the head of the stud. It is inserted by first taking the head in the fingers and introducing the movable shank b, and then pressing the bend of the said shank against one end of the hole till the said shank is slid as far as possible inward in the slot d, and pushing the fixed shank (Z, into the hole as shown in Fig. 4C, and then relieving the head from the pressure of the fingers and allowing the spring Z), to force it toward the opposite end of the hole to that over which the shank b, is hooked and so to force the fixed shank d, beyond its end of the hole. The stud or button will then bear turning in any direction and will remain secure till it is desired to remove it, when the head is taken hold of and the shank o, pressed against either end of the holes, till the shank cl, can be drawn out and this being done the stud or button can be removed.

What I claim as my invention and desire tosecure by Letters Patent is:

The combination of the movable hook like shank b, applied to slide in a slotin the back of the head and the spring c, applied to the said shank to operate as described in combination with the fixed hook like shank b.
